formatDatetime giving wrong month

(0) ShareShare
ReportReport
Posted on by TR-23071229-1

I have a flow variable to find the first day of the previous month which gives me the correct date (but it adds a time)  I want to format the date to be mm-dd-yy

 

addtoTime(startOfMonth(addToTime(utcNow(),-1,'month')),0,'day')

value = 2020-01-01T00:00:00.0000000Z

 

When I add formatDateTime to the variable it gives me a wrong month

 

formatDateTime(addtoTime(startOfMonth(addToTime(utcNow(),-1,'month')),0,'day'),'mmmm-dd-yyyy')

Value = 00-01-2020

 

Any help would be appreciated

    @trentskirush in Power Automate the month part of the expression must always be in upper case, i.e MMMM. Lower case is used for minutes.

    @RobElliott- thanks - I was thinking that might be it, but never got around to trying that.  thanks for the clarification.
